Q: Mail issues after 10.11.1 upgrade

Since updating to 10.11.1 Mail is impossibly slow, up to an hour to send even small messages, have rebooted.


My ******@yahoo.co.uk messages sat in outbox also show a sender address as ****@me.com , I have never used this.


Safari also slow when Mail is running. Any ideas?

MacBook Air (11-inch Mid 2012), OS X Yosemite (10.10.2)

    Back up all data before proceeding.

    Step 1

    If Mail crashes or freezes immediately on launch, try the steps suggested on this page. Sometimes a corrupt message on a mail server can be deleted by logging in to the server through its web page. If Mail still won't launch, or if you can't take Step 2 for any other reason, skip to Step 3.

    Step 2

    There are three types of mail account: IMAP, Exchange, and POP. You can determine the type of each account by opening the Mail preferences window, selecting the Accounts tab, and then selecting Account Information.

    Select all POP mailboxes, if any, and then select

              Mailbox ▹ Export Mailbox...

    from the Mail menu bar. Export the POP mailboxes to the Desktop folder.

    If you have IMAP or Exchange accounts, and you don't store sent, deleted, and junk messages on the server, export those mailboxes the same way. You can determine whether the messages are on the server by selecting Mailbox Behaviors in the Accounts tab.

    Also export all mailboxes in the On My Mac category.

    You don't have to export the other mailboxes, because the messages are stored on the servers.

    Quit Mail.

    Step 3

    In System Preferences, open Internet Accounts (OS X 10.9 or later) or Mail, Contacts & Calendars (OS X 10.7 or 10.8). Make notes of the settings for each mail account (all types), then delete the accounts.

    Step 4

    In the Finder, hold down the option key and select

              Go ▹ Library

    from the menu bar. Move the following items (some may not exist) from the folder that opens to the Desktop:

              Application Support/AddressBook/MailRecents-v4.abcdmr

              Containers/com.apple.corerecents.recentsd

              Containers/com.apple.mail

              Containers/com.apple.MailServiceAgent

              Containers/com.apple.share.Mail.compose

              Mail

    Note: you are not moving the Mail application. You’re moving a folder named “Mail.”

    Step 5

    Launch Mail. It will behave as if you were setting it up for the first time. Go through the setup process with one account, using the information from Step 3. Test. If Mail works now, recreate the rest of the accounts (if you have more than one) and other settings.

    Any custom stationery that you created may be lost. Ask for instructions if you want to preserve that data.

    If there’s no improvement, quit Mail and put back the items you moved to the Desktop, replacing any newer ones that may have been created in their place. Stop here and post your results.

    Step 6

    If you took Step 2, import the mailboxes you exported:

              File ▹ Import Mailbox...

    Select Apple Mail as the data type. Typically, the process takes a few minutes, but it may take hours if you have gigantic mailboxes. In that case, you may be able to speed things up by temporarily adding your home folder to the Privacy list in the Spotlight preference pane. Remove it when Mail has finished importing.

    The mailboxes that you didn't export in Step 1 should synchronize automatically with the server. Again, if the mailboxes are very large, downloading them may take quite some time, and network performance will be slower than usual during that time.

    If you skipped Step 2, look inside the Mail folder on the Desktop for a subfolder Mail/V2/Mailboxes. Import the mailboxes it contains.

    Test. If Mail is still working, delete the items you moved to the Desktop in Step 4.

    Thanks Linc, this has resolved my issues. My accounts are all IMAP and stored on the server.

     

    I couldn't see the subfolder Mail/V2/Mailboxes although there is one in V3, however, everything looks ok so I did not import this.

     

    Thanks again,
